Sony Xperia Z2 records 4K video


Sony has launched the latest iteration of its Xperia Z-line of flagship Android smartphones. The Xperia Z2 looks like a solid upgrade to the Z1 but overall the changes are more evolutionary than revolutionary. At 5.2-inches, the Z2's 1080p display is slightly larger than the Z1's 5-inch variant and the edges on the new model are a little more rounded, but the design with the the glass panels encased in an aluminium frame hasn't changed much. At 8.2mm the new model is a touch slimmer but still waterproof and dust-resistant to the same standards as before (IP55 & IP58).

Under the hood things are now powered by the same components that you can also find in the new Xperia Tablet Z2. A Snapdragon S801 quad-core processor and 3GB RAM should allow for smooth operation of Android 4.4 and the 16GB of built-in storage can be expanded via a MicroSD-slot.

The Z2's glass front and back are encased in a one-piece aluminium frame.
The new model is capable of recording 4K video.
The external stereo-microphone STM10 looks like an interesting accessory for serious videographers.
The SmartBand SWR10 connects to Sony's Lifelogging app.

With a 20.7 MP 1/2.3-inch CMOS sensor the camera specifications look identical to the Z1 but the new model is now capable of recording 4K video. For those who are serious about video recording Sony also offers the external stereo-microphone STM10. 

While the camera hardware looks the same as in the previous generation, some new software features are available in the camera app:

  • Timeshift Video captures at 120 frames and allows you to slow down portions of your footage for dramatic effect.
  • Creative Effect offers a range of new effects for both video and stills, including color, image trails, mirror and motion effects.
  • Background Defocus simulates a shallow depth of field by capturing two photos at different focus settings and blending them.
  • AR Effect was already available for still images on the Z1 but works now with video, too. It adds augmented reality animations to your images and video.
  • Vine4 creates short video loops that are easily shareable. 

The Xperia Z2 also comes with the same noise-cancelling technology as the Tablet Z2. Ambient noise can be reduced by up to 98% when the device is used with the new MDR NC31EM noise canceling headset. Along with the Z2 Sony also launched the SmartBand SWR10 that talks to the Lifelog app on your Android smartphone via Bluetooth and NFC. By doing so it creates a diary of your activities and also measures your sleep cycle and vibrates to notify you of calls, messages, tweets or other events. 


  • Qualcomm Snapdragon 801 2.3 GHz quad-core processor
  • Android 4.4 KitKat
  • 3GB RAM
  • 16GB storage, MicroSD support up to 64GB
  • 5.2-inch Full-HD (1920 x 1200) TRILUMINOS display
  • 20.7 MP 1/2.3-inch Exmor RS for mobile CMOS sensor
  • 4K video recording  (3840×2160 pixels/30p)
  • 2.2 MP front camera
  • Dust-resistant and waterproof (IP55 & IP58)
  • NFC
  • 3200 mAh battery

Hey everyone, I'm a new user here so I'll just get straight into it.

I have the samsung 4k monitor, as well as this phone. I would like to connect the two to watch the 4k photo's and video's (in 4k!) so i am wondering how to conntect the two with the full quality?



I'm so fed up with the intrusive bloatware of Samsungs (like, say, Samsung Mobile folder in Chrome (!) browser than not only can't be deleted, but to which I'm switched -- forced -- once in appr. 20 times I open bookmarks), that Xperia does not even have to be "great", it just has to be "good enough" to be my next phone...


How much is the Sony Xperia Z2?


Which rating is it? IP55 or IP58. Both rating are on the same scale so there shouldn't be two.

Hi Peiasdf

It is 58 in normal IP terms (logic behind both numbers is supposedly that the device has not been tested for IPx6 that corresponds to strong water jets, therefore the double digit)


Looks nicer than the Samsung GS5. I'd rather have a better camera & lens than a fingerprint reader and heart rate monitor. Plus I'm a Samsung owner now and I'm really tired of the cheap plastic shell, that's the one thing that has made me envious of the iPhone. The glass and aluminum casing on this one put it into Apple's league as to looking and feeling like a high quality product.

Is the battery removable?

Also, does Sony have a good history of providing Android updates or do they tend to strand you with what it came with?


That's why my Wife turned from a Galaxy to iPhone. The Samsung feels like junk. Fingerprint activation is brilliant by the way, so it's worth having on any phone.

i'm currently using the Xperia Z. battery is not removable; only phones with "cheap plastic shell" as you mention allows for removal of battery.

Android updates: regular enough, have no complains.


This really does look like a great phone. All of the latest and greatest.

Gotta wonder if the screen is IPS or not though.


IPS according to specs.


Problem is: you never know. Check the exact device before purchase, as Sony loves the prototype trick - they put IPS into prototypes and send them for reviews, install IPS into those phones sold in Japan, and install a much cheaper TFT screen into the rest of the phones (they did so with Z1). Make sure you're satisfied by the screen before purchase.
"Its a Sony" Sony that makes best of the best is a thing of the past, sadly.


It may shoot 4K, but the chip+optics is great if it resolves more than 600 lines vertical.

So much for specsmanship...


Well, actually, the Z1 had pretty good effective resolution too - definitely over 8 Mpixels (that is, 4K).

It was the noise of the high-Mpixel small sensor that let the Z1 down, not the lack of effective resolution.

I don't think the Z2 would be significantly worse, resolution-wise.

All in all, I more than welcome the 4K recording. We'll see how it fares against the Samsung Note 3 / Samsung GS5 / LG Pro 2's 4K recording...

It will resolve better than 600 lines vertical if it's like the Note 3 4K.


Do you have a 4k TV to watch 4k vids? I certainly don't, I'd rather buy a new sedan than a 4k TV.


"Do you have a 4k TV to watch 4k vids? I certainly don't, I'd rather buy a new sedan than a 4k TV."

Nevertheless, if you have some precious moments to save, it's advisable to shoot in 4K even today, unless it has a severe impact on other parameters like maximal shooting time or the inability to use any kind of stabilization while shooting, unlike with 1080p shooting (the case with the Note 3).

There's an excellent writeup on why 4K shooting should be preferred, even if you (now) don't have a 4K TV / monitor, at - I *really* recommend it.


I don't understand the reasoning behind the 20Mp, surely one would want to improve image quality by having larger sensing elements at this level. I reckon 16Mp would have been more than sufficient for phone use. The extra real estate could then have been used for noise reduction.

if this works the same way as the Z1, and it almost certainly will, you can set it to 20MP but the default setting is 8MP. The image is captured at 20MP and then downscaled to 20MP. Noise is averaged out and detail sharpened, similar to the recent Nokia Lumias.


basically packing more pixels into same sensor area should not harm or increase image quality other than pixel resolution, but for semiconductors smaller pixels may mean higher efficiency.
